From fe4860af002a4516dd878f7297b61e186c475b35 Mon Sep 17 00:00:00 2001 From: Jose Alberto Reguero Date: Sun, 3 Feb 2013 19:30:38 -0300 Subject: [PATCH] [media] [PATH,1/2] mxl5007 move reset to attach This patch move the soft reset to the attach function because with dual tuners, when one tuner do reset, the other one is perturbed, and the stream has errors.
